本文提出了钢纤维高强砼软化应力-应变关系。应用软化桁架理论,对钢纤维高强砼低剪力墙的受力全过程进行了分析。结果表明,计算理论值与试验结果符合程度较好。在此基础上,提出了低剪力墙抗剪能力的计算公式。
This paper presents the softening stress-strain relationship of steel fiber high-strength crucibles. Applying the softened truss theory, the whole process of the steel fiber high-strength concrete low shear wall was analyzed. The results show that the calculated theoretical values are in good agreement with the test results. On this basis, the formula for the shear capacity of low-shear wall is proposed.
